Abstract
A privacy keypad providing privacy for keypad character entry and concealment of a joint in an escutcheon. A privacy keypad may include a faceplate, a keypad disposed on the faceplate, and at least one protrusion integral with the faceplate. An escutcheon for a door lock may include a housing, a keypad disposed on the housing for unlocking the door lock, and at least one protrusion integral with the housing. The protrusion may obstruct at least partially a line of sight to the keypad. An escutcheon may include top and bottom covers with the top cover projecting outward from the surface of a door more than the lower cover, resulting in an at least partially hidden joint between covers. Top and bottom covers may be interchangeable with covers having similar edges.
